THIMBLE-EMBOSSING MACHINE.

SPECIFICATION'forming part of Letters Patent No. 426,407, dated. April 22, 1890.

Application filed January 22, 1890. Serial No. 837,675. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH BROWNING, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Thimble Embossing Machines, of which the following is a specification.

My invention relates to machines for embossing thimbles and other articles; and it consists of certain improvements, which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

More particularly my invention is an improvement upon the machine set out in Letters Patent No. 407,637, granted to me on the 23d day of July, 1889. In that patent is illustrated an apparatus in which the thimble or article to be embossed is supported by a rotating spindle, and an embossing-wheel is rotated in contact with the surface of the thimble for the purpose of imparting ornamentation to it, the embossing-wheel being operated by a hand-lever, and, by means of suitable gearing between the shaft of the embossingwheel and the thimble-carrying spindle, mo-' tion is imparted to the latter. The embossing-wheel and its shaft are supported in a suitable frame, which is adjustable to and from the thimble-carrying spindle.

The present invention consists in certain improvements in the power-transmitting devices whereby the motion is imparted to the thimble-spindle, and in improvements in the embossing-wheel, and in certain other details, which are hereinafter more fully set out and claimed.

In the drawings, Figure 1 is a side elevation of a thimble-embossing machine embodying my improvements. Fig. 2 is a horizontal sectional view of the same on the line 00 cc of Fig. 1. Fig. 3 is a side elevation, 011 an enlarged scale, of the detached embossing-wheel, with the thimble in section. Fig. 4. is a sectional view of the same on the line y 'y of Fig. 3, and Fig. 5 is a section through part of the gearing.

A is the bed-plate or main frame of the machine, mounted on suitable legs a a.

B is a sliding frame mounted on the bedplate A on suitable guides.

O is a vertical shaft journaled in the frame A and carrying a spindle 0, upon which the thimble or other article to be embossed is supported.

D is the embossing-Wheel, a portion of the surface of which (Z is provided with ornamentation, which is adapted to rotate in contact with the surface of the thimble for the purpose of imparting thereto the ornamented or embossed effect.

Carried by the slide B is a block F, by means of which the angle of the embossing wheel may be adjusted, as is set forth in the patent heretofore referred to. V

G is a sleeve carried by the slide B and passing through the block F. Through the sleeve G is arranged a tubular shaft H, which carries on its upper end the embossingwheel D.

K is the handle by which motion is imparted to the embossing-wheel D.

H is a bevel-gear meshing with a gear I, carried by a shaft J, journaled in an arm or bracket B of the slide B, under the base-plate or frame A.

L is a gear-wheel also carried by the shaft J, below the gear I, and meshing with the teeth of a gear M, journaled 011a stud m, carried by a lever N, which is pivoted to the shaft 0.

The gear-wheel L is arranged loosely upon the shaft J and is connected with the pinion I through a friction device best shown in Fig. 5. From this figure it will be seen that resting upon the inner face of the gear-wheel L is a fiat disk L, which is secured by feather 3', so as to rotate with the shaft J. The pinion I is provided with a sleeve 2', upon which is a nut, I. By screwing the nut I down upon the disk L friction is produced between the said disk L and the gear-wheel L, and while normally the pinion I and gear-wheel L will rotate at the same velocity, yet if the diameter of the spindle c or the thimble is less than what the machine is especially designed for, then the pinion I may have a slightly different velocity of rotation than the gear-wheel L.- This construction prevents any possibility of the embossing-Wheel D rotating at a faster velocity than the thimble, and thereby stripping the embossed surface from the thimble. This construction enables meto use the same machinery for thimbles of different diameters and produce at the same I ried by a shaft Q, extending up through the frame A, and provided on its upper end with a gear P, meshing with the pinion R, carried by a clamp S, which is provided with a spindle s, passing up into an orifice in the end of an adjusting-screw T, carried by a bracket a of the frame. By means of this adjustingscrew T the clamp S is forced down upon the thimble to hold it securely upon the spindle 0.

E is an adjusting-screw for adjusting the slide B to or from the Spindle c.

O is a link connecting the stud m of the lever N with the shaft J whereby the gears M and L are kept in constant engagement.

In the apparatus described in Letters Patent No. 407,637, referred to, are shown devices for withdrawing the slide from the thimble sufficiently to remove the latter from the spindle, consisting of an arm pivoted to the slide and fitting between the end of the screw E and the slide. To accomplish this object in the present apparatus I dispense with this pivoted arm and the movement of the slide and form the embossing-wheel D with the notches D D on the sides and near the ends of the engraved or ornamented portion d, so that when the embossing-wheel D has been rotated in contact with the thimble or other article andthe embossed or ornamented surface applied thereto the thimble may readily be removed from the spindle 0 through the notches D without any movement of the slide 13.

From the foregoing description the operation of the apparatus will be understood.

The thimble or other article to be embossed is placed upon the spindle c and the clamp S thimble or other article which is to be embossed or ornamented. The operation of the handle K imparts a motion'to the shaft II and .its beveled gear H and thence to the gear I of the shaft J, by which the gear L is rotated. This gear L transmits motion to the gear M, carried on the stud m of the lever N and thence to the pinion O, which rotates the shaft 0, carrying the thimble-supporting spindle 0. Motion is imparted to the clamp S by means of the gears P and P on the extremities of the shaft Q, the one meshing with the pinion O of the shaft 0 and the other with the pinion Rof the clamp S. By moving the lever N it will be seen that the pressure of the gear M upon the gear L will move the slide B upon its guides on the frame or base-plate A, so as to bring the surface of the embossing-wheel D nearer to or farther from the axis of the spindle c to suit different embossingwheels or articles of different sizes, while the link 0 between the stud m and shaft J will keep the gears M and L in constant engagement. When the ornamentation has been imparted to the thimble or other article and the embossing-wheel D has been turned so that its notches D are in line with the surface of the thimble, the latter may be removed from the spindle 0 through these notches D without any movement of the slide I).

WVhile I prefer the details of construction which are here shown I do not limit my invention to them, as it is apparent that they maybe modified in many ways without de-' parting from the spirit of it.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an embossing-machine, the combination of a support for a thimble or other article, and an embossing-wheel having a portion of its surface provided with ornamentation and having one or more notches on its side to permit the movement of the thimble or artiole from the support after it has been ornamented or embossed.
